May be it is me... I'm starting with Hibernate and have downloaded the examples from "Getting Started" (http://www.hibernate.org/152.html)

I believe that the test whereby the description for AuctionItem 3 should change does NOT work, further test do not work in turn.

Looking at the log, it seems to fetch the right row (I've tried the query independently and it does not throw any exception). However, it does NOT update the row as you can see in the log with SQL.

Is it a known problem (sorry if I repeat it here then), or am I doing something wrong? I have followed the instructions to the letter (can't really go wrong with the ant build etc)

Hibernate version: 3.0.5

Mapping documents: as per 'Getting Started' example

Code between sessionFactory.openSession() and session.close():
try {
tx = s.beginTransaction();

AuctionItem item = (AuctionItem) s.get(AuctionItem.class, itemId);
if (item==null) throw new IllegalArgumentException("No item for the given id: " + itemId);
item.setDescription(description);

tx.commit();
}
catch (Exception e) {
if (tx!=null) tx.rollback();
throw e;
}
finally {
s.close();
}

Name and version of the database you are using: MySQL 4.0.1

The generated SQL (show_sql=true):
....Here is the output for that section...
[java] Changing auction item description for: 3
[java] Hibernate: select auctionite0_.id as id0_, auctionite0_.seller as seller0_0_, auctionite0_.description as descript3_0_0_, auctionite0_.end
s as ends0_0_, auctionite0_.condition as condition0_0_, auctionite0_.successfulBid as successf6_0_0_ from AuctionItem auctionite0_ where auctionite0_.
id=?
[java] Viewing user and auctions: 1

There is NO UPDATE before the next test...


Any suggestion welcomed!
Many thanks!

regards from London

Hello

Here is the more detailed log of the "eg" application provided with hibernate 3.0.5.

I'm running MySQL but in any case, the log does not show any UPDATE where I believe it should...

the test
Code:
test.changeItemDescription(mainItem.getId(), "new description");


is supposed to change the description of AuctionItem id 3 from "auction item 2" to "new description". This in turn is used in some test
Code:
test.viewAuctionsByDescription("DESC", 8);


Unfortunately, the description is NOT changed.
Code:
id     seller     description     ends                   condition     successfulBid   
-----  ---------  --------------  ---------------------  ------------  ----------------
3      1          auction item 2  2005-07-09 10:21:30.0  8             (null)           


To me, it looks like the test is failing under hibernate 3.0.5!

Could anyone confirm this, as it is after all the first hibernate application that I run...

The XML for the AuctionItem is the one downloaded with Hibernate 3.0.5, left unmodified:
Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
   "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
   "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping
   package="org.hibernate.auction">

   <import class="AuctionInfo"/>

   <class name="AuctionItem">
      <comment>An item that is being auctioned.</comment>
      
      <id name="id">
         <generator class="native"/>
      </id>
      
      <natural-id>
         <many-to-one name="seller"/>
         <property name="description"
               length="200"/>
      </natural-id>
            
      <property name="ends"/>
      
      <property name="condition"/>
      
      <many-to-one name="successfulBid"
            outer-join="false"/>
      
      <bag name="bids"
            inverse="true"
            cascade="all">
         <key column="item"/>
         <one-to-many class="Bid"/>
      </bag>      
   </class>      
</hibernate-mapping>


And the test code, again, unmodified from the hibernate distribution:
Code:
/**
* Demonstrates automatic dirty checking
*/
public void changeItemDescription(Long itemId, String description) throws Exception {
   System.out.println("Changing auction item description for: " + itemId );

   Session s = factory.openSession();
   Transaction tx=null;
   try {
      tx = s.beginTransaction();

      AuctionItem item = (AuctionItem) s.get(AuctionItem.class, itemId);
      if (item==null) throw new IllegalArgumentException("No item for the given id: " + itemId);
      item.setDescription(description);

      tx.commit();
   }
   catch (Exception e) {
      if (tx!=null) tx.rollback();
      throw e;
   }
   finally {
      s.close();
   }
}

...
test.changeItemDescription(mainItem.getId(), "new description");
...


The log below shows the detailed trace of that particular test, other tests show the SQL select/insert/update but this one has NO update.

Any help would be greatly appreciated, I'm a bit surprised to see an issue in the main demo... but it could be me...

Best regards
